Floating-Point Formats

The Compiler supports two IEEE floating-point formats: IEEE32 and IEEE64. The processor may also support a DSP format. The following listing shows these three formats.

Floats are implemented as IEEE32 and doubles as IEEE64. This may vary for a specific Backend, or possibly neither format is supported. Refer to HC(S)08 Backend for details, default settings, and supported formats.

The topics covered here are as follows:

• Floating-Point Representation of 500.0 for IEEE
  
  
• Representation of 500.0 in IEEE32 Format
  
  
• Representation of 500.0 in IEEE64 Format
  
  
• Representation of 500.0 in DSP Format
